UNITED STATES GEORGE STOFF, OF CANTON, OHIO.

VALVE LIFTER.

Application led November 20, 1924. Serial No. 751,034.

To all 'whom t may concern.:

Be it known that I, Grieken SroFF, a citi* zen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Valve Lifters, of which the following is a specification.

This invention relates to tools for use in removing valves from valve-in-head motors and more particularly to a device for compressing the valve spring and holding the same in an elevated position permitting the valve stems to be disconnected therefrom and removed with the valves.

The above and other objects may be attained by providing a relatively stationary upright having an angular jaw and a relatively movable upright, slidably connected therewith, and provided with an angular jaw, and manually operable means for actuating the movable upright and securing the same in adjusted position; the severalparts involving a novel construction and arrangement whereby the power may be conveniently applied and the device capable of being easily and readily fitted to the valve mechanism of an internal combustion engine to admit of the valve spring being compressed when it is desired to release or secure the valve.

' An embodiment of the invention is illustrated in the accompanying drawing, in which-` Figure 1 is a side elevation of the im proved tool, parts being broken away for the purpose of illustration; and

Fig. 2, a l'ront edgeV elevation of the same.

Similar numerals of reference indicate corresponding parts throughout the several figures of the drawings.

The tool comprises the normally stationary upright 1, which is preferably inclined Slightly backward as shown and provided at its lower end with the angular horizontally disposed jaw 2, the free end of which is bifurcated as at 3, providing a. claw or fork.

A tubular guide 4 is fixed to the upright l and the relatively movable upright 5 is slidably mounted therein and provided at its lower end with the angular horizontally disposed jaw 6, the free end of which is bifurcated as at 7 to provide a jaw or claw and arranged to normally rest upon the j aw 2 as shown in dotted lines in Fig. 2 and in full lines in Fig. 1.

A vertical flange 8 is formed along each side edge of the jaw 6 to accommodate the usual spring` 9 and collar 10 upon the valve stem 11.

An operating lever 12 is ulcrumed intermediate its extremities, as shown at 13 upon the upper end of the normally stationary upright 1, and the forward end of the lever is connected as by the link 14 with the upper end of the movable upright 5.

In operating the tool to compress the valve spring, the jaw 6 is placed in position upon the jaw 2 as shown in Fig. 2 and in dotted lines in Fig. 1, and the forks of the jaws are inserted beneath the vave spring and washer, the i'orks receiving the lower end of the valve stem.

The operating lever 12 is then depressed, raising Jr.he movable jaw 6, as illustrated in Fig. 1, compressing the spring 10.

In order to hold the parts in this position to permit the operator to remove the pin 15 from the valve stem, a link 16 may be pivoted at one end to the operating lever and provided with a plurality of notches 17 for engagement with the stud 18 upon the stationary upright 1. l

The tool may thus be held in this position while the pin 15 is removed, permitting withdrawal of the valve and in replacing the valve the tool may be used in the same manner, it being only necessary to disengage the link 16 when itis desired to disengage the tool from the valve.

From the above it will be obvious that the advantages of the tool are simplicity and cheapness of construction; similarity of operation and eliciency, as the spring ma be compressed tothe desired point and ield by latching the operating lever in adjusted position, permitting the operator to remove both hands from the lever to remove the pin from the valve stem.

I claim 1. A tool of the character described, including an inclined normally stationary upright having an angular jaw at its lower end and provided with a tubular guide, a movable upright slidably mounted in said guide and provided at its lower end with a bifurcated jaw normally contacting with the stationary jaw, a lever pivotally connected intermediate its ends to the stationary upright, and a link pivotally connecting one end of the lever to the upper end of the movable upright .for raising the movable S il jaw out of Contact with the stationary jaw.

2. A tool of Ythe character described, in-

cluding an inclined normally stationary np- 2 right having an angular iaw at its .loWerrY 5 end, and provided with atubular gnide,a inovable upright slidably mounted Vin said guide and provided at its loive-r end with `a bfureate'd jaw normally contacting Ywith the stationary jaw, a lever -pivotally connected 10 intermediate its ends to the stationary np- GEORGE STUFF.
